"Does a more perfect handheld food than onigiri exist? A classic onigiri at O.Onigiri with spam, egg and teriyaki sauce will only run you $6, but even the fancier varieties, with fillings like shrimp tempura, unagi, and soft shell crab, are all under $10. Vegetarian options include onigiri with plant-based Spam, curry tofu, or purple yam tempura." - Janna Karel
